IDCAMS ALTER and GDGs - From A(0) to B(+1) - Relative Generations
I'm looking at a customer batch job and they are rolling over 12 monthly files by 1 - the oldest going off to another data set on tape. They are doing this with ICEGENER copy steps. Each monthly file is a different GDG. Rather than do the actual copying I'd like them to explore using some form of rename. In this case it boils down to renaming FILE1(0) to FILE2(+1). IDCAMS ALTER will do it with hardcoded generations and versions. I checked this and that the structure of the target GDG was intact - by coding some JCL on my own system. However, I'd prefer not to have to recommend absolute generations and versions. Does anyone know how to do this with (0) and (+1)? Yes, I'm aware there may be some operational difficulties with this approach - we didn't keep n generations this way. I'm not convinced the customer actually wants to. I want to present them with options.

Re: CTC Connectivity
Scott Rowe wrote: The CTC connectivity report does not work for these types of definitions, since it has no way of knowing that the two channels are connected to each other. It has always been this way for ESCON/FICON CTCs without a switch. A good example of where RMF can't be reliably used to glean configuration. But in this case the data it has access to doesn't support that line of enquiry. Another, perhaps more trivial, one is the absence of PCHIDs in Type 73. (CHPIDs are there but not PCHIDs.)

Job Numbers rolling over
In some SMF from a customer I see Job Numbers rolling over - i.e. Starting at 1 again - around midnight. And this happens when the old Job Numbers never approached the limit. (I only have overnight 1/2 September so don't know if this is regular.) I'm wondering how this could be... Some kind of restart (cold really needed) or $T NUM are the two methods I know of. I'm not just interested in the mechanism but also what people think are useful practices. Likewise this IS JES2 but JES3-related answers would also be interesting. (Facebook users will have seen me witter on about analysing Job Numbers to see which jobs the scheduler threw into the hopper at the same tiem - else I wouldn't be looking at Job Numbers in the first place.)

But this one has me stumped: I'd like to be able to create a scatter plot where the x value is meaningful - not successive integers and not x values used as labels. Does anyone know which GDDM PGF options to use to get this particular axis semantic working. (Bonus points for how to drive ICU to define a ADMCFORM that does this, given I know how to drive ICU to the point of getting a scatter plot.) The above is probably pretty obscure but I'm thinking IBM-MAIN has the best chance of remembering. :-) Thanks, Martin Martin Packer, Mainframe Performance Consultant, Software Group Worldwide Banking Center of Excellence, IBM +44-7802-245-584 email: martin_pac...@uk.ibm.com Twitter / Facebook IDs: MartinPacker Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.

Re: DFSORT - Avoid reading entire input file?
STOPAFT is indeed the right one... STARTREC and ENDREC are OUTFIL statements and therefore downstream from where the file is read. (I'm sure Frank will correct my terminology in a few hours' / days' time.) :-) STOPAFT is upstream and so the reads don't take place once the STOPAFT value has been reached.

Re: Library Lookaside
IIRC it's BOTH LLA and VLF that do the heavy lifting... LLA buffers directories in its own address space and passes modules via class CSVLLA to VLF. That's how I learnt it in 1988.

While the standard 32 ALIAS that most people are deploying for HyperPAV is plenty in most cases, I just been working with one account where 32 is plainly not enough and they are getting some significant IOS Q time - averages of 400ms and max of 800ms. In general a small number of Alias will work well with small service times, but if you have volumes with many concurrent IO and large service times it is pretty easy to eat up those aliases very quickly. In this case it is the 32K DSNDB07 tables, but it could easily be any other volume with many large chained IO, or a occasional sibling pend problems.

Re: EMC DASD and Hyper-PAVs
Ron, just to fill in some DB2 background (as a z/OS guy who's done a fair amount of interloping in DB2). :-) DB2 Sort Work data sets, whether 32KB or some other size, are buffered by standard DB2 buffer pools. (Often these buffer pools are dedicated to sort work data sets for management and reporting purposes. Indeed in my reporting code on the matter - fed by the DB2 Catalog - I could tell if this was the case.) It's entirely feasible to resize these buffer pools (using the normal DB2 buffer pool mechanisms) and to play with their sequential and update thresholds. If you make them big enough you might be able to reduce the amount of DB2 sort I/O. Not that that would NECESSARILY change the profile of the I/Os (which is I guess your gist). Hoping that helps a little.

There is a 3), of course: 3) We - as PEOPLE - are less good than some others about portraying mainframe folks as a vibrant COMMUNITY. There are some notable exceptions, of course.

Re: MaxSpace and Real Memory
Others have spoken on this and they've spoken well... I've seen a situation such as yours, albeit with slightly smaller numbers. The 8GB virtual requirement turns into 8GB real or (more probably) 8GB of mixture of real and aux. There's a trade-off here (and I think it has the opportunity to be a fairly unpleasant one): Too small a value and you get partial dumps (with the potential for partial fixes). :-) Too large and you have real memory and paging space consumption issues. For what it's worth, and this is part of the reason for replying, I think we need to develop a better understanding of how dumping works - from the address space perspective... Some products are pretty smart at dumping (though maybe could be smarter) deploying techniques such as sequencing dumping in an appropriate way and avoiding dumping the whole of large (largely fruitless) areas. There are probably other tricks but I'm not close enough to it to know. So, a question: Would it be helpful to have documented a snapshot of how eg DB2, CICS, WAS, WMQ, IMS etc dump? I've thought so for some time and would be quite willing to attempt to collate some of this - with the help of relevant development groups. In a way I've already started: My Memory Matters presentation now has some stuff on dumping and configuring for it. I suspect most of my audience wonder why. It's PRECISELY for situations like yours that I think the material worthwhile. So, for example, suppose we only got the first 4GB of a 10GB DB2 DBM1 dumped before the space ran out. What's the impact? Similarly, suppose 10 CICS regions dump in parallel and we run out part way through? Etc etc. And back to the original question: Some installations take a dump must be ultra-fast event stance and others take a we can't afford huge amounts of idle memory stance. I think installations need to take SOME stance, though it's probably going to be in between these two. Thoughts?

Re: VIO Storage Group
If one were looking at CPU, though, it might be a different matter... Long long ago in a decade far far away was The Coffee Table Book. :-) Or so I called the Data In Memory studies orange book. It showed the results of a number of performance studies conducted by Poughkeepsie (and possibly other labs). Some of the fine people who did the studies may very well be watching IBM-MAIN. :-) One of the things I remember is that over a number of data points the VIO to Expanded Storage study showed a net CPU cost for using VIO to ES over regular temporary data sets. The folklore suggested that this was due to simulating a real (then 3380) device via VIO. Recall it maintains the illusion of PHYSICAL I/O to real disk volumes. Now, things may have changed. In particular it's not Expanded Storage but Central. But I doubt the device simulation aspect has changed much. So I would be cautious on CPU for VIO to Central against SSD.

ADMUGIF REXX Sample - ADMGDF To GIF Conversion
Ultimately I'm trying to convert ADMGDFs into JPEGs (though I guess GIFs have similar utility). Does anyone have a sample invocation - either JCL or (preferably) REXX for invoking ADMUGIF to convert ADMGDFs to GIFs? In particular I want to convert from one member of a PDS to another member. I have to confess the GDDM documentation for ADMUGIF is pretty crummy - especially on file allocation for the GIF PDS. If HFS would be a better target data set I'll countenance using that instead of a PDS. The other route is to take the CGMs my process already creates and convert them somehow to GIF or JPEG. Possibly on z/OS in Batch or maybe on Windows. Though I don't know of a good batch conversion program. As give back I'll happily document - in my blog - how to do this. (I'll obviously acknowledge those who help me in this quest.)

Re: Is there a tool to put SMF data into DB/2?
I use SLR every day - though unsupported for 15 years. It does NOT use DB2. It uses VSAM. The use of VSAM is what makes SLR attractive to me... That's because I create and allow HSM to migrate fresh performance databases for each customer situation (and often several). Running unsupported - FOR ME - is a minor risk as I do almost all the development of our tooling (including mapping SMF records).

Memory Instrumentation - was largest parallel sysplex around?
As someone who sees A LOT of customer systems I regularly see customer machines with over 100GB purchased (and often well over 200GB installed but not all purchased). I see this information in Vital Product Data. Given that RMF Development put machine serial number in Type 70 for me I can pull the stunt of going to the Vital Product Database and getting the information - even down to which book how much is on. My mantra is machines should be self-documenting and in that vein I perceive value in RMF learning how to get things like: Installed Memory and how much of that is purchased. HSA Size (and yes I know it's fixed 16GB on z10) How much memory each LPAR has reserved. NONE of the above is in plan. My discussions with RMF take me to the hardware folks. I've only just started talking to them about this topic. What I'd like to understand is whether you all feel there's value in having these numbers in SMF 70. I suspect the answer is more positive for installations with several CECS with many LPARs. But what about people with simpler environments? As I think you can gather I can promise nothing other than to take the discussion to Development teams with the appropriate expectation of value for customers. And as success in this would probably involve enhancements to hardware you'll know it's not an immediate prospect. (Enhancements to Type 70 that externalise what's already given by the hardware HAVE been quick to appear (almost overnight in one recent case) but that's not the case here.)

Re: Add Storage To Lpar - z/800
Standard plea to customers: Find out how much memory you actually have on each machine and ensure you deploy the right portions of that as reserved to the right LPARs. (This is not the only situation this quarter where a customer was forced to IPL to add memory out of idle to an LPAR.) And standard plea to Development (which I WILL take forward if I can): Have RMF able to report the installed memory so customers can figure out what they've got idle. (Also that installed but not purchased would be good.) And, no, it's not there right now. But, on z10 having the HSA a standard 16GB was a good idea - or at least so it seems so far. So customers don't have to ask for an API to report HSA size via RMF. (But we could still use one.)

I'll only reply to this answer to avoid cluttering up the list. I suspected that I probably couldn't add any storage to this Lpar without at least an IPL. Both of LP01 and LP02 have 2 GB defined for real storage, and 1GB in reserve. I believe the 1GB in reserve gets varied online just after the IPL, as both systems show 3072 MB in storage after a D M=STOR command. I did find out that HSA is 128M, and with LP03 LP04 being at 512M, I should have 896M available to add to LP02, which is our DB2 Lpar. I'm not sure if I can add that amount or not - I'll have to figure out what the increment size is. I'm sure we could easily remove 1 GB from LP01. It runs normally around 5-10% busy, unless I'm running SMP stuff or someone else is running batch. It also has zero paging, and no DB2. The transaction volumes are falling on that Lpar, and it will be phased out in the near future. Thanks for the quick replies.

Sysplex MAXSYS - Impact Of Under- Or Over-Specifying
What are the impacts of getting MAXSYS wrong for a Sysplex?

I can see it might be disruptive to increase the MAXSYS value if you need to add a system in and MAXSYS would prevent you.

Re: XCF Coupling Facility Space vs In-Memory Buffers
Barbara, here's my point... You can think of XCF as a queuing mechanism between members on (potentially) different systems in the plex... The mechanism has various queuing areas (whether it be buffer pools in memory owned by XCF or coupling facility list structures). Conventional wisdom has it that one configures the buffer pools large enough and one doesn't worry too much about the size of the coupling facility structures - in that you use CFSizer to size them and don't bother tuning from there. I'm wondering whether one wouldn't be better off making the structures bigger and (perhaps) the buffer pools in the z/OS systems smaller. In other words, what are the trade offs for biasing towards space in the CF list structures vs biasing towards space in XCF buffers in z/OS? I'm not sure that makes it any clearer. :-) Martin Martin Packer Performance Consultant IBM United Kingdom Ltd +44-20-8832-5167 +44-7802-245-584 [EMAIL PROTECTED] Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.

XCF Coupling Facility Space vs In-Memory Buffers
For once *I* get to ask a question. :-) And perhaps a stoopid one. :-) As many of you - especially those who follow me on Twitter - know, I'm writing the Performance Metrics chapter of the new Redbook on Parallel Sysplex Performance... It has occurred to me that one can treat XCF as a sophisticated queuing mechanism and that path, transport class, and local buffers are really subqueues. As are the lists in any Coupling Facility List Structures you might use for XCF. So, I'm wondering whether it's better to place the memory centrally in the CF structures. Or distributed via the various in-memory buffer pools. And, yes, I know CTCs don't have an in-built queue (other than the buffer pools I've already mentioned). Note: Though we use the term buffer pool these aren't reread-amenable areas of memory (unless there's something missing from MY understanding). So I'd be interested in your opinions.

They refer to eg CFLEVEL1 which I kinda think all customers will have by now. :-) Martin Martin Packer Performance Consultant IBM United Kingdom Ltd +44-20-8832-5167 +44-7802-245-584 [EMAIL PROTECTED] From: Brian Kenny [EMAIL PROTECTED] To: IBM-MAIN@BAMA.UA.EDU Date: 22/07/2008 14:15 Subject: Re: z/OS 1.9 System Commands Memory Reconfiguration Issue Recently, June 2008, with time on my hands and no real life, I got tired so seeing references in the EREP reference (copyright Mar 2006) to the 3081 and 3090s. So summoning up righteous indignation I sent off an email to the address in back of the manual - [EMAIL PROTECTED], never really expecting a response. Surprise, about a week later I received an email from IBM thanking me for my input and a promise that the manuals would be changed with the next release. Thankfully my workload has increased and I am no longer spending my time in search of nits to pick. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.

Re: z/OS 1.9 System Commands Memory Reconfiguration Issue
That WASN'T my assumption... My assumption was that anyone WITH a CF had it well above CFLEVEL=1. As to WHAT the minimum level is I don't know. Rich Fochtman wrote: Bad assumption. I'm stuck working part-time in a Basic Sysplex shop of three images: PROD, TEST and SANDBOX. CF is not even being considered, mainly due to politics in the office. All three images running in separate LPARs on a 6-engine z9 processor.
